General Description
The MAX3873A is a compact, low-power 2.488Gbps/
2.67Gbps clock-recovery and data-retiming IC for
SDH/SONET applications. The phase-locked loop (PLL)
recovers a synchronous clock signal from the serial NRZ
data input. The input data is then retimed by this recov-
ered clock, providing a clean data output. The MAX3873A
meets all SDH/SONET jitter specifications, does not
require an external reference clock to aid in frequency
acquisition, and provides excellent tolerance to both
deterministic and sinusoidal jitter. The MAX3873A pro-
vides a PLL loss-of-lock (LOL) output to indicate whether
the CDR is in lock. The recovered data and clock outputs
are CML with on-chip 50
Ω back terminations on each line.
The clock output can be powered down if not used.
The MAX3873A is implemented in Maxim’s second-gener-
ation SiGe process and consumes only 260mW at 3.3V
supply (output clock disabled, low output swing). The
device is available in a 4mm x 4mm 20-pin QFN
exposed-pad package and operates from -40°C to +85°C.
